Dorchester’s most expensive areas for buying include Savin Hill, Lower Mills

The most expensive areas of Dorchester for buying a home as of early March are Lower Mills, Savin Hill, Neponset-Port Norfolk, Uphams Corner-Jones Hill, and Cedar Grove, according to an analysis of market-rate listings from real estate research site NeighborhoodX.

That is because homes in those parts of Boston’s largest neighborhood by area are currently asking on average more than Dorchester’s overall average price of $319 a foot.

As for the more affordable areas of Dot, those include Fields Corner and Codman Square—and Mattapan. NeighborhoodX included in its analysis Mattapan, which was once part of an independent Dorchester before the latter’s 1870 annexation to Boston.

The analysis also reflects Dorchester’s diverse housing stock as well as access to public transit and local amenities, according to NeighborhoodX research director Constantine Valhouli, who compiled the handy breakdown below.
